You bring up a good point. Ocean salinity has been studied for more than 300 years and the best that can be said is that salinity of ocean water varies. On a similar vein,global warming has been studied for about 30 minutes by comparison and we are getting all sorts of wild speculations propagated by alarmists as facts. Let's just wait for them to see that, given more time, their alarming predictions are not based on long term data but on short term data that has been edited and culled to promote a particular dogma.
Back to salt, let's not always rely upon favorite evolutionist propagandist sites for information. This is from
Mysterious Changes in Ocean Salt Spur NASA Expedition,
http://www.livescience.com/22954-changes-ocean-salinity-voyage.html Here are quotes:
Over the past 50 years, the salty parts of the oceans have become saltier and the fresh regions have become fresher, and the degree of change is greater than scientists can explain.
I suppose it is back to the drawing board and time to scrap all the old Talk Origins articles long held in undue high esteem by devout evolutionists. Here is more:
By tracking ocean salinity, researchers can better understand the global water cycle. Global warming is expected to intensify it, but current computer models do not predict the amount of change seen over the last 50 years, Schmitt said.
Here is a wonder. Scientists have studied salinity for 300 years and have mapped data and have tied that study into the global warming research, but the facts are not lining up with their computer models. Wonder of wonder.
No wonder Al Gore messed up in predicting New York City would be under global warming flooding by 2005, a promoted truth he no doubt now finds inconvenient.
